This dessert blends a bottle of stout with chocolate for something truly magical. You'll taste deep, malty notes from the Guinness mixed with rich cocoa in an incredibly moist cake. The coffee-infused frosting tops it off perfectly. Every bite shows off complex flavors you won't find in regular chocolate cake.
I baked this cake for my buddy's birthday party, and when I poured the Guinness into the melted butter, everyone in the house came running to the kitchen because it smelled so amazing.
Key Ingredients and Shopping Advice
- Guinness: Use it at room temp for better mixing; don't worry if it's gone flat
- Cocoa Powder: Go for Dutch-processed for a deeper color and taste
- Sour Cream: Get the full-fat kind for extra moisture
- Coffee: Brew it fresh but let it cool completely
- Butter: European brands work best in both cake and topping

Step-by-Step Walkthrough
- Making the Guinness Mix:
- Watch your Guinness-butter combo carefully. Take it off the heat when bubbles start showing up at the edges. Once you add cocoa, start whisking right away so you don't get lumps.
- Mixing Wet Stuff:
- Getting the temperature right matters a lot. Make sure the Guinness mixture feels just barely warm before you add it to the eggs and sour cream, or they might curdle.
- Adding the Flour:
- When you put in the flour, fold it gently instead of stirring hard. Stop once you can't see flour streaks anymore. If you mix too much, your cake will turn out tough.
- Whipping Up the Frosting:
- Your butter should be just slightly soft—firm but giving a little when pressed. This way your powdered sugar blends in right and won't turn greasy.
- Putting it Together:
- Tuck parchment paper strips under the cake edges while frosting to keep your plate clean. Just pull them out when you're done for a neat look.

My grandma always told me that adding beer to baking was like using a magic ingredient that turns ordinary into something special. I see she was right every time I make this cake.
Clever Layer Building Tips
There's a trick to stacking and frosting this beauty:
- Cut each layer flat while they're still a bit warm
- Put on a thin layer first and chill it for 15 minutes
- Start spreading filling from the middle outward
- Make the edges a bit thicker than the middle for better stability
Getting Temperatures Just Right
Temperature plays a big role in success:
- Let ingredients warm to room temp for smoother blending
- Cool your layers briefly in the fridge before adding frosting
- Set finished cake out for 1-2 hours before serving
- Store somewhere cool but not directly in the fridge
Topping Like a Pro
Getting that perfect coffee frosting:
- Begin with butter that's just slightly soft
- Mix in coffee bit by bit to avoid separation
- Whip it for 5-7 minutes until it's light and fluffy
- Keep a little warm frosting ready for quick fixes
Fixing Common Problems
If the middle sinks:
- Make sure your oven temp is right
- Don't overbeat the batter
- Keep the oven closed during first 25 minutes
- Check if your baking soda is still good
If it turns out dry:
- Take it out when a few moist bits stick to your tester
- Cover it properly when storing
- Brush with coffee syrup if needed
